Although both are a _little_ bloated, they adhere at least minimally to
the Unix philosophy of each tool doing one thing well, rather than
trying to do everything in one tool. So, I would be _dismayed_ if they
added that.
We've seen the end-result of feature-itis and "integration" before, and
it's not pretty. (Hell, OpenOffice.org is something of an offender.)
So, most of us try not to go there.
